What Is Acid Washing?
Acid washing is a deep cleaning process that uses a diluted muriatic acid solution to strip away a thin layer from your pool’s surface, typically plaster or concrete. It is one of the most effective cleaning methods to remove tough pool stains, including algae growth, calcium deposits, and mineral deposits caused by hard water or metals.
The acid washing process targets areas where regular cleaning does not cut it, restoring your swimming pool to a cleaner, brighter, and more pristine condition. If your pool bottom, pool walls, or pool tile have lost their luster and you’ve tried scrubbing with little success, an acid wash service may be the solution your pool needs.
When Does a Pool Need an Acid Wash?
Not sure if your Charleston pool needs acid washing? Here are a few red flags:
- Stubborn stains on the pool surface that do not lift with brushing
- Visible calcium buildup or mineral buildup along pool tile or plaster
- Green pool appearance due to long-standing algae growth
- Faded or dingy surface even after regular cleaning
- The pool looks aged, neglected, or has sat with stagnant water for too long
If you notice these issues, a pool acid washing service could give your pool’s appearance the reset it needs.
Benefits of Acid Washing
There’s a reason acid washing is a go-to service for neglected or heavily used pools.
Benefits of acid washing include:
- Restores Bright Surface Color: Brings back the crisp, clean, white appearance of your pool plaster surface.
- Removes Years of Buildup: Cuts through layers of mineral stains, dirt, and chlorine residue.
- Improves Aesthetic Instantly: You’ll see a dramatic aesthetic improvement, often making the pool look like new.
- Prepares for Resurfacing: Offers a perfect prep step if you’re planning to resurface your pool in the future.

Frequently Asked Questions
Can I acid wash my pool myself?
It’s not recommended. Muriatic acid is dangerous to handle, and improper application can damage your pool plaster. Let our professionals handle the process safely.
How often should a pool be acid washed?
Typically, every 3 to 5 years, depending on usage, water chemistry, and staining severity. Overuse can wear down the pool surface, so acid washing is best done only when needed.
Will acid washing remove all pool stains?
Most, yes, especially mineral stains, algae, and chlorine stains. However, deep etching or old surface damage may need resurfacing afterward.
Is acid washing safe for all pools?
Acid washing is ideal for concrete or plaster pools. If you have a vinyl liner or fiberglass pool, we can help you explore safer cleaning process options.
How long does it take to acid wash a pool?
The full process, including draining, washing, refilling, and balancing the pool water, usually takes 1 to 2 days.
What is the difference between acid washing and chlorine washing?
Chlorine washes are gentler and primarily used to address algae growth or biofilm. Acid washes are stronger and are designed to remove mineral buildup and restore pool surfaces.
Will I need to rebalance the pool afterward?
Yes. After an acid wash, we’ll help adjust your pool water chemistry so it’s swim-ready and safe.
